Portion of a display screen for a self-propelled working machine with graphical user interface



FIG. 1 is a front view of a portion of a display screen for a self-propelled working machine with graphical user interface showing our new design; and,

FIG. 2 is a partially enlarged view of the portion surrounded by the alternate long and short dash lines in FIG. 1 of the front view thereof.

The broken-lines depicting a frame of display screen for a self-propelled working machine and a centered vertical line in FIG. 1 and FIG. 2 form no part of the claimed design. The alternate long and short dash lines in FIG. 1 and FIG. 2 define, but are not included in, the boundaries of the claimed design.
